Clayton County Police Officer SeanCallahan waskilled in the line of duty Monday. The 24 year old from Kennesaw was fatally shot while responding to a call about a domestic dispute at a Motel 6in Stockbridge.

He was laid to rest in his hometown Friday afternoon.

More than 2,000 cars and motorcyclestook part in the procession before and after hisfuneralatJohnson Ferry Baptist Church in Marietta. His family and friends say they were grateful forthe sea of blue.

"It's amazing. Just the brotherhood of the police officers that are here. It's incredible to see all the police officers that showed up, not just from Clayton county," said Ben Thomason.

Several of the officers that were with Callahan the day he died, still struggle with the shooting.

"I know there are a lot of officers in our department right now still emotionally torn by the situation. Even when you talk with them, they choke up. So it's really affecting our department," said Clayton county police Lt. Thomas Reimers.

Callahan's family says he had hoped to use his love of dogs and passion for police work, to help the K-9 unit.

Callahan had only been with the department for four months when he died. A former co-worker remembers when he left his office to join the force.

"I hugged him twice and I said, 'Sean is this what you really want to do?' And he said, this is what he really wanted to do," said George Demas.

Clayton County Commissioner, and former police officer,Eldrin Bell declared December 21st would be a day the community would always pause to remember his sacrifice and life.
